When I try run app on linux server with php version: 5.4.23 I have a warrning:
"call_user_func() expects parameter 1 to be a valid callback, no array or string given"
and my app doesn’t work
On windows and php v 5.4.22 it works correct
Any suggestion ?
what code are you referring to? Please post the code or say which file and line of the framework you refer to.
1. in vendor/yiisoft/yii2/base/Component.php at line 546
537538539540541542543544545546547548549550551552553554555
$event = new Event;
}
if ($event->sender === null) {
$event->sender = $this;
}
$event->handled = false;
$event->name = $name;
foreach ($this->_events[$name] as $handler) {
$event->data = $handler[1];
call_user_func($handler[0], $event);
// stop further handling if the event is handled
if ($event->handled) {
return;
}
}
}
// invoke class-level attached handlers
Event::trigger($this, $name, $event);
}
so this looks like you regsistered an invalid event handler.
I din’t register any own event. In stack trace I see:
Stack trace:
#0 [internal function]: yii\base\ErrorHandler->handleError(2, 'call_user_func(...', '/home/th175382/...', 546, Array)
#1 vendor/yiisoft/yii2/base/Component.php(546): call_user_func(NULL, Object(yii\base\Event))
#2 vendor/yiisoft/yii2/base/Application.php(350): yii\base\Component->trigger('beforeRequest')
I don’t understand why it’s work on my local machine, a don’t on the remote 
There must be something that registered an handler to the beforeRequest event. If it was not yourself it may be some extension or an application behavior.
Can you show your composer.json file and the application config?
Yes, composer is stndard yii advance template

does the problem also exist with a fresh install of the advanced app without any changes?
yes I install fresh php
composer.phar create-project --prefer-dist --stability=dev yiisoft/yii2-app-advanced /path/to/yii-application
and it’s the same error.
I use composer on my local machine and then move files via ftp, does it matter ? I should use composer on remote server ? (I don’t permission to console )
In Yii requirements I have:
PDO SQLite extension - warning
Memcache extension - warning
APC extension - warning
Expose PHP - warning
ON localhost:
I have only APC extension - warning
Can it be the reason ?
